Description

MTHHOD AND SYSTEM FOR DISPLAYING GROUP CHAT SESSIONS ON WIRELESS MOBILE TERMINALS}

This application is filed on September 18, 2002 and is a continuing application of US Patent Application No. 10 / 245,918, entitled Text Group Chat Technology for Voice and Wireless Mobile Terminals, which is a patent application for voice and text group chat for wireless mobile terminals. US Patent Application No. 10 / 197,022 filed on July 17, 2002 entitled Display Management Technology. The contents of these applications are incorporated herein.

The present invention relates to a wireless communication system comprising voice and text input and output modality, and more particularly to an improved technique for literally providing real time conversation (chat tread) on the display of a mobile unit. will be.

Text and voice chat systems are known in the prior art, in particular in the prior art for personal computer systems. Published US patent application 2001/0042095 A1; 2001/0011293 A1; 2002/0023128 A1 and US Pat. Nos. 6,212,548 and 6,286,034 illustrate exemplary systems and user interfaces used today. A common feature of such a system is that the various conversations (or threads) are typically separated into separate areas (or windows) on the display or screen. Moreover, if a single thread contains both multiple text and voice exchanges, these systems are separated into two forms. Voice is typically played on a speaker, while a plurality of text messages are displayed on the screen. Users have no means of referring to old speech messages or identifying when old voice messages occurred in that thread with respect to other messages in the thread.

Published US Patent Application 2002/0023128 A1 (" 128 Publication ") describes a system in which the screen area is divided into six separate windows. While one window shows the chat history of one thread (the focused thread), another window displays the chat history of multiple remaining threads combined. The chat history is displayed on the screen describing both inboubd (i.e. received by the user mobile terminal) and outbound (i.e. sent by the user terminal) chat messages. Contains entries of. This entry is typically displayed on the screen in chronological order and typically describes only text messages.

Although the chat system described above satisfies the needs of some chat group users, the system focuses primarily on the large screen of the personal computer. Visible areas on the screen are given specific functions. These interfaces are not very suitable for systems with small displays. Small screen devices, such as mobile devices that provide exclusive areas for text entry or other transition functions, consume valuable screen area. This arrangement prevents the device from fully utilizing the available screen display if the transition function (eg when editing a new message) is not used.

Common execution on a mobile device changes the user through a series of screens. For example, when editing a message, conventional practice on a limited screen device moves the user from a chat history screen that occupies the entire content display of the screen to a text editing screen that also occupies the content display of this screen. . This configuration prevents the user from viewing the chat history because the user progresses in real time while composing the message. If there is an incoming message, the user must go back to the history screen to see if the currently configured message is related to providing the content of the received message. A user interface that solves such problems greatly improves the desirability and convenience of joining a chat session. Thus, in view of the limitations of mobile devices, a wireless messaging system with an improved user interface in a mobile unit that allows simultaneous editing of chat threads and compositions and / or response messages can be displayed. Need to provide

It is an advantage of the present invention to provide an improved method and system for managing both single mode (i.e. voice or text) and multiple mode (i.e. combined voice and text) wireless chat services.

Another advantage of the present invention is to provide a mobile terminal interface that allows the user to configure the message in response to the currently viewed chat message while simultaneously allowing the user to view the chat session in real time.

In accordance with an embodiment of the present invention, a wireless system enables chat-based communication between mobile terminals. Each mobile terminal includes a display screen that can provide chat message text, a graphical user interface and other information. At least some of the terminals run a chat client application that provides a chat service over a wireless carrier network. A mobile terminal running a chat client can display a chat conversation that is updated in real time or near real time so that messages in the conversation gradually scroll on the screen. In addition, the chat client allows the mobile terminal to simultaneously present a chat conversation on another part of the screen, while providing a text editing area on the part of the screen. The text editor present in the mobile terminal allows the user to compose a message in the text editing area while simultaneously viewing the chat conversation as the user progresses. The configured message may be a response to the conversation currently being displayed.

Once the operation of composing and delivering the message is complete, the chat client allows the mobile terminal to remove the text editing area and enlarge the chat history area to occupy a freed screen area.

Other systems, methods, features and advantages of the present invention will become apparent to those skilled in the art upon examination of the following figures and detailed description.

The invention will be explained in detail with reference to Figs. 1 illustrates a wireless mobile terminal 100 that may include a wireless communication device such as a portable cellular phone or a wireless PDA. The configuration of the mobile terminal 100 shown in FIG. 1 is merely exemplary and in general, it is understood that various terminal and terminal configurations may be used. As shown, the mobile terminal 100 includes a speaker 103 for providing a signal such as received voice, sound; A display 102 that enables viewing of textual graphical components; A navigation locker 105 for allowing a user to navigate a list or menu displayed on the sprinkler; Programmable button (ie, softkey) 104; A keypad 106 that allows a user to enter digits, letters, and other symbols (portraits); A microphone 107 for capturing audio such as a user's voice; And a push-to-talk button 101 for allowing a user to start recording and transmitting audio. These and other components (not shown) of the mobile terminal are known in the art and will not be described herein any further. In addition, there are several ways or examples that may be used instead of (or in connection with) the components shown in FIG. 1. For example, push-to-talk button 101 can be removed and an automatic voice detection mechanism can be used. Touch screen and handwriting recognition techniques can replace the need for soft keys 104, navigation lockers 105, and keypad 106. The present invention is not limited in this respect. Additional components of the terminal which are not necessary to be visible to the user but which are necessary for performing the chat functionality are further described with reference to FIG. 3. Input devices available on a wireless mobile terminal (e.g., keypad, softkey, etc.) may be used by a user of the wireless mobile terminal to initiate a session of chat software, and within the operation of the chat software, one or more chat conversations, as described below. Start threads (threads).

2 illustrates the overall system architecture of a wireless communication system including a plurality of mobile terminals 100 according to an embodiment of the present invention. Terminal 100 communicates with one or more chat server complex 204 by wirelessly transmitting data to a corresponding wireless carrier infrastructure 202. As is known in the prior art, the wireless carrier infrastructure 202 includes the elements necessary to support wireless communication with the terminal 100. Various service providers (such as Verizon or Sprint in the United States or Organge in Europe) build and maintain this infrastructure. After the data packet is delivered to the communication network 203 it is delivered to the server complex 204. A communication network 203, which is a packet-based network, may include a public network such as the Internet or the world wide web, a private network such as a cooperating intranet, and a combination of public and private network elements. The server complex 204 can include a plurality of networked server computers that can be programmed to perform the functionality described below. The specific number of servers used and the way they communicate with each other is a matter of design choice. Techniques for programming server computers and mobile terminals are known in the prior art.

When the server complex 204 communicates with one or more mobile terminals, the server complex 204 forwards the data to the network 203 and then to the one or more carrier infrastructures 202. Each associated carrier infrastructure 202 delivers data to one or more corresponding mobile terminals 100. Preferably, when a plurality of users chat together (i.e., transfer a chat message from terminal 100 to another terminal), text, voice, and / or graphical messages (or combinations thereof) are received by server complex 204. Is passed on. The server complex 204 delivers copies of the following message to the targeted terminal 100, which in one embodiment includes the initial or transmitting terminal.

The server complex 204 may be located inside the wireless carrier infrastructure 202 or may be removed if direct end-to-end transmission is supported. In the latter case, all chat message functionality is substantially supported by the mobile terminal. Moreover, the present invention will benefit not only systems limited to the scope of the domain of a single wireless carrier, but also systems other than packet data based systems.

In a preferred embodiment, one or more chat server complexes 204 reside outside of the carrier domain. For this reason, it is possible to service a plurality of mobile terminals 100 that may be associated with a plurality of wireless carriers. The system disclosed herein is, in fact, independent of the wireless operators. This system does not require any particular hardware or software to be located within the operator wireless network 202. The wireless operator network (with respect to the public network 203) serves as a communication pipe between the mobile terminal 100 and the server complex 204. Preferably, using a standard packet data transmission protocol, such as mobile terminal 100, Internet protocol (IP), transmission control protocol (TCP), user datagram protocol (UDP), and hypertext transfer protocol (HTTP). Route data messages back and forth between server complexes 204, such as the World Wide Web Protocol. Server complex 204 acts as a gateway between the various transport protocols. The plurality of mobile terminals 100 may be connected to the chat server complex 204 using an appropriate transport protocol. The message is sent from the mobile terminal 100 to the server complex 204 via one or more protocols. The server complex 204 copies the content of the message and sends it to the intended receiving mobile terminal 100 using an appropriate transport protocol suitable for the targeted mobile terminal 100.

3 shows very detailed components that can be seen in server complex 204 mode used to exchange group voice and text chat messages with terminal 100. Looking at the components of the terminal 100, it is preferred that the mechanically readable and executable instructions (generally software, code or program) are stored in the application storage (or memory) 310 and the centralized unit (CPU) Is executed at 211. All storage devices described include combinations of volatile (eg random access memory) or nonvolatile (eg read only memory) storage devices, as is known in the art. Similarly, CPU 211 may include a microprocessor, a digital signal processor, a common processor, similar devices, and combinations thereof. Using known programming techniques, the software uses the I / O controller 312 to control the display 102 and to capture voice from the microphone 107, the keypad 106, the navigation locker 105, soft keys. Input data is captured from 104 and / or push-to-talk button 101. Inbound chat messages received from the server complex 204 as well as outbound chat messages delivered from the server complex 204 pass through a network interface 306 that provides connectivity between the terminal and the data network. When terminal 100 includes a wireless device, network interface 306 communicates with server complex 204 and includes the entire physical interface including a wireless transceiver. Preferably, the speech delivered to the server complex 204, although not necessarily necessary, is performed in software, but is preferably encoded first using speech code 307, which may preferably be performed in a combination of hardware and software components. Similarly, if necessary, the voice from server complex 204 is decoded using voice code 307 before the voice is delivered to speaker 103. The software uses temporary storage 309 to store task data that does not persist between software initiations (sessions). Software, on the other hand, allows data to exist for a longer period of time that can span multiple software sessions using persistent storage 305.

Looking at the components of the server complex 204, the decoded voice and text messages (eg, outbound chat message 400: see FIG. 4) are delivered to the server complex 204 across the router 301. The router 301, the presence message 302, the message broadcaster 303, and the nickname manager 304 may be performed on one or more server computers or the like present in the server complex 204. The router 301 directs the outbound chat message 400 toward the requested plurality of inbound chat message copies (e.g., inbound sieve message 500; see FIG. 5) and the message broadcaster 303 which determines the destination. do. In the context of this specification, inbound refers to a message destined for one or more mobile terminals, while outbound refers to a message delivered by a mobile terminal. Message broadcaster 303 constructs an incoming message 400 and locates a list of reception identifiers 402. Presence manager 302 to set the recipient's current state 702 (ie, an indicator indicating whether the recipient is ready to receive only certain types of messages, voice and / or text messages) and the terminal's address 703. Queuing 7 illustrates a table in which a plurality of presence data records 700 are included in the presence manager 303. Each record 700 includes a public display identifier and its record, such as user identifier 701, current state 702, current terminal address 703 (if known), public nickname 704, and public short name 705. And a plurality of different user identifiers 706 that have signed the presence information of the user corresponding to. The public display identifier or public nickname set 704-705 allows the recipient (ie, the receiving user) to override the public nickname set 704-705 with the personal display identifier or private nickname set 802-803. If the current state 702 is changed, the presence manager 302 delivers to all the subscribers listed in the subscriber identifier field 706 of the presence record 700 corresponding to the buddy list update message 600. Presence record 700 may include attributes such as transport address and other information, processing rules describing what to do in different environments, representations and profiles for various states (i.e., may be used at various times or at the receiver). A plurality of sets of different values depending upon).

Although not shown in FIG. 3, server complex 204 may include other components such as cryptographic servers and authentication to ensure the authenticity of chat communication messages and to ensure the privacy of these content. This server complex 204 is more important by receiving voice to text and text to voice translators, natural language translators, voice transcoders and messages, their content and attachments (e.g., ring-tones, images, etc.). And a plurality of other components, such as other similar conversion gateways that convert to the available formats. Techniques for performing these other components are known in the prior art.

In a preferred embodiment, each of the plurality of radio operators is configured with different wireless data technologies and code division multiple access in a wireless carrier network 202, such as Mobile Communications (GSM) General Packet Radio Servic (GPRS). Single carrier radio transmission technology (1 × RTX) of CDMA. In other respects, the systems disclosed herein do not depend on the data radio technology employed.

In a preferred embodiment, the voice code 307 used in the plurality of mobile terminals 100 is provided for the terminal. The voice coder 307 provided to the mobile terminal 100 is optimal for both the terminal processing strategy and the radio technology employed. The system utilizes a commercially available media program gateway (not shown) so that the system is independent of the underlying wireless technology. This media gateway transcode voice samples from the encoding to another entering. In operation, the message broadcaster 303 sets the type of encoding used on an incoming message. This determines the type of encoding required for each of the plurality of target mobile terminals 100. For each copy of the message, the message broadcaster 303 uses one or more media gateways to transcode the voice into a coding program appropriate for the target recipient. Techniques for detecting the type of interfacing to the media gateway as well as the encoding used by the incoming message and required by the target terminal are known in the prior art. Processing when the media gateway cannot meet the conversation can be performed by the system. For example, the message is passed back to the sender and informs that the message has not been delivered to the target recipient because it does not support the transcoding technology required by the system. In addition, the system can be configured to optimize transcoding. For example, the message broadcaster 303 may reuse the same transcoding for message target mobile terminals that require the same decoding. In addition, when the message broadcaster 303 detects that it cannot be delivered to the target, the broadcaster can prevent transcoding voice. Other optimization techniques can of course be used.

In a preferred embodiment, a plurality of mobile terminals 100 are grouped and assigned among the plurality of chat server complexes 204. For this reason, each server complex 204 services a set of specific mobile terminals 100 that require the same voice decoding. Multiple server complex 204 may use the same encoding. When a message reaches the message broadcaster 303 of one of the chat server complexes 204, the broadcaster may send one or more copies of the message to another server complex that manages the connection with a subset of the intended recipients of the message. 204). The forwarded message is transcoded by the media gateway of the rotor between the two server complexes 204. An advantage of a system that uses a common encoding to transmit voice is to sample between several server complexes 204. In particular, the message received by the server complex 204 is transcoded into a common encoding and then passed to a plurality of other target server complexes 204 (in this case only one transcoding is required). When a message arrives at each of the plurality of destination server complexes 204, the message is converted to the encoding appropriate for the target mobile terminal 100. Since all terminals served by this complex use the same encoding, only one encoding in the end server complex is required. Messages that are not delivered outside the server complex 204 do not require trans encoding because the mobile terminals served by the complex use the same encoding. In this configuration, only gateways are deployed between complexes 204 because only the gateway needs to transcode content between the encoding used by the mobile terminal 100 served by the complex 204 and the common encoding. In addition, the detection of the required type of transcoding is inherent in the routing of messages, i.e., the structure and distribution of the mobile terminal, and therefore does not require a practical solution based on any encoding information itself. This is solved only on the basis of the target address of the mobile terminal being resolved in all cases of routing and directing the message. For example, instead of using the multiple server complex 204, a plurality of message broadcasters 303 may be subdivided when used with the same intention as the distributed server complex 204. The present invention is not limited to the specific configuration of the server complex. Alternative configurations may be used for the server complex.

Preferably, the nickname manager 304 is in the server complex 204 to manage the list of nickname sets 802-803 used by the recipients of the inbound chat message 500 to override the public nickname and short name. Take responsibility. It should be noted that the nickname and short name are different in principle. Nicknames can have any length (as limited as possible by the content of the design choice), while short names are preferably fixed in length or size. In addition, nicknames and short names are examples of display identifiers used to identify the originator of a chat message. Such display identifiers are distinguished from identifiers intentionally used by the system to identify a particular user (this identifier is 701, 403 and 604 in the accompanying figures). Also note that the short name may be different from the nickname in format or format. The system can use compact, fixed size graphics, symbolic and other appropriately formatted short names while using the text format for nicknames. The system can change graphics and symbols based on content, user preferences, presentation theme and personality.

8 illustrates a nickname record 800 contained within nickname manager 304. Preferably, each nickname record 800 includes a receiving user identifier 701, a body identifier 801 (i.e., a buddy public nickname set 704-705) and a recipient personal nickname set 802-803 for all inbound chats. An identifier of the chat buddy for which the receiving user wants the message broadcaster 303 to replace the message 500), a personal nickname 802, and a personal short name 803. As is the case with the presence record 700, the nickname record 802 may be used for attrition and other information, such as forwarding addresses, processing rules, graphical presentation of various states, profiles (i.e., at various times). Different field values). Upon receiving the targeted message for the recipient designated by the receiving user identifier 701, the nickname manager 304 determines the buddy identifier 801 (ie, the identity of the chat originator of the message originator). Based on the buddy identifier 801, the nickname manager 304 retrieves a nickname record corresponding to the target recipient. If no buddy identifier is found in the nickname record of the mocked recipient, the message is delivered to the intended recipient as an inbound message with the sender's public nickname and public short name. In this case, the sender's public nickname and / or short name will be displayed on the intended recipient's mobile terminal display. The nickname manager determines the personal nickname and personal short name associated with the buddy identifier and replaces the public nickname with the personal nickname and / or public short name with the personal short name as a series of inbound messages delivered to the intended recipients. The name will be displayed on the recipient's mobile terminal display. In this way, the user (ie, the recipient) has great control over how the chat story is displayed on these terminals. It should be noted that the process of determining the personal display identifier and replacing it with the public display identifier is performed by the mobile terminal to infer that the necessary nickname record has been stored in the mobile terminal.

4 illustrates an outbound chat message 400 from which the terminal 100 is delivered to the message broadcaster 303. This outbound chat message 400 may include a message type (e.g., text, voice, etc.), a plurality of intended recipients 402, a plurality of recipient identifiers 403, a thread identifier 404, a message length 405 , Message content 406, and a plurality of attachments 407. Preferably, the mobile terminal 100 generates a thread identifier 404 by adding the client identifier and the work duration identifier to the thread sequence number. The thread sequence number is a terminal-side number starting at 0 each time the session starts. Whenever the terminal 100 generates a new thread, the client increments the thread sequence number by one. Although not shown in FIG. 4, the play pad may include a message encoding type and other attachments (eg, icons, ring-tones, etc.). Other components may be added to outbound chat messages such as sequence numbers, time stamps, and the like.

Upon receiving the outbound chat message 400, the message broadcaster 303 determines the sender identifier (eg, the first recipient identifier in the recipient identifier list 403) and a plurality of other recipient identifiers (ie, identifiers other than the sender recipient). The list of target recipients (including the recipient identifiers in list 403) is first compiled. For each target, the message broadcaster 303 determines the target's state 702 by placing the identifier of the target in the presence record 700 with the matching identifier 701. For a valid target, the broadcaster manager 303 constructs an inbound chat message 500 (ie, if the presence record indicates that the recipient can receive the message type 401). The message broadcaster 304 queues the nickname manager 304 to find the receiver local nickname set 802-803 for the other recipient (ie, the identifier includes the original list of targets without the recipient's identifier). If no information is found (ie, the receiver does not build a nickname record 800 for a particular recipient), the message broadcaster 304 may send the current message 302 for the recipient's public nickname information 704-705. Queuing). The message broadcaster 303 extracts the recipient's address 703 from the presence manager 302 and transmits the inbound message 500 to the receiver's terminal 100 via the router 301. Those skilled in the art will appreciate that means for optimizing the generation and broadcasting of messages, such as using generic compression and encoding techniques, may be used and other information may be included in the inbound chat message 500, such as sequence numbers and time stamps, and the like. will be.

5 shows an inbound message 500 sent by the server complex 204 to the terminal 100. As shown, the copy of the outbound chat message transmitted from the terminal 100 to the server complex 204 is mostly. Inbound message 500 includes the definition of a new user not known to the terminal and the original outbound message 400 (ie, it is not already present in the recipient's buddy list). The new user definition includes a number of new definitions 501 and a plurality of individual definitions including the recipient's identifier 502, full name 503, public nickname 504, and public short name 505. In some cases, the original outbound message must be translated so that the receiving terminal 100 can understand it. It should be noted that the server complex 204 may need to include its new customization only during the session. This user definition is located in the temporary storage device 309 of the terminal 100. This causes less wireless data transmission. Other attributes may be placed in an inbound chat message that includes things such as time stamps and sequence numbers. It should also be noted that anonymous identification and virtual or group identification may of course be used.

If the participant present state 702 is changed, the message broadcaster 303 forwards the buddy list update message 600 to other users subscribed to the participant present state 702.

6 shows a buddy list update message 600 sent from the server complex 204 to the mobile terminal 100. The message 600 may include a list form 601 (e.g., an abbreviated list of numbers, a group list, etc.), a number of groups identified in the message, one or more group definitions, a list of ungrouped individuals 605-606, and A plurality of user definitions 502-505, 607 are included. Note that the receiver status field 607 indicates the value of the current status 702. The group definition in this content includes a group name 603 and a plurality of recipient identifiers 604. The identifier of the receiver may be present in the plurality of group definitions. However, there will preferably be only user definitions 502-505, 607. Moreover, preferably for each identifier in the list of identifiers 604 of the recipient, there is one or more user definitions 502-5-5, 607 for the recipient in the buddy list update message 600. The list of ungrouped individuals is a special unnamed group. This includes a number of ungrouped individuals 605 and a list of recipient identifiers 606. Preferably, the recipient identifier in an ungrouped definition cannot be in another group. Record 600 may include other fields of information and attributes, such as presentation icons, audio icons, and the like. In addition, it should be noted that the message does not have to include an entire list of groups and individuals at the time of update rather than incremental updates being used instead.

When the presence manager 302 receives the refresh request from the terminal 100, the presence manager 302 transmits a buddy list update message 600 to the terminal 100. Those skilled in the art will recognize buddy list updates (e.g., initial access) as well as other reasons for sending optimizations in the form of encoding content and sending incremental updates instead of the entire list.

In another embodiment, some (or all) of the functionality of the message broadcaster 303 and the nickname manager 304 may reside on the terminal 100. In that case, the terminal 100 communicates with the server complex 204 when exchanging with the presence information. The chat communication manager is transmitted from the terminal 100 to the plurality of other terminals 100 in a point-to-point manner.

9 illustrates a buddy list display with entries stored alphabetically. Screen 102 is divided into three regions. At the top is a title bar area 901 that allows display of one line of text and graphic symbols (ie, icons). The software uses this area 901 to provide user information and meta-information about the current task. For the buddy list display, the title bar 901 includes the user's own presence indicator 904, the user's own public nickname 704, and the inbound chat message indicator 905. Preferably, the presence indicator 904 is an icon that the current state 702 changes depending on the shape it depends on (ie, there are different and distinguishable characteristics associated with the various state values). Preferably, inbound chat message indicator 905 is an icon accompanied by sound when the icon is first displayed. Viewable and audible information informs the user that there is an inaudible and unread inbound message 500 that has reached the terminal 100. If the user's nickname is too long for the title bar 901, the software scrolls the title bar leaving the inbound chat message indicator 905 in a fixed position for quick access. There are many similar examples of such displays today and are incorporated herein.

In the middle area of the display is a content area 903. In the case of the buddy list display, the software preferably places a plurality of selection lists in the content area 903, which list is sent from the server complex 204 to the terminal 100 in the buddy list update message 600. Is an area received by and stored in temporary storage 309. Each entry is highlighted 908 by the user. Highlight and navigation list entries are performed using generic techniques. Each entry in the list is a selection indicator 906 indicating whether the user has selected a particular buddy for chat (i.e. sending a chat communication message), the buddy's presence indicator 911, the buddy's nickname 802 or 704 And / or the short name indicator 907 of the buddy. The non-text symbol functions as the short name indicator 907 for the short name information 705 or 803, as described previously. For example, icons or other graphical components can be used as long as they recognize differences in buddies from each other.

At the bottom of the screen 102 is a softkey label region 205. Preferably, there are at least two labels 909-910. The number of labels depends on the actual number of softkeys 104 available at terminal 100. As shown, if there is more than one selected entry in the buddy list, the left softkey label 910 is "selected" while the right softkey label 909 is "write." Otherwise, the right softkey The label 909 is labeled “Chat.” If the user activates the left softkey with a single click (called a single click forward), the highlighted entry 908 is selected (if not already selected). This selection indicator 906 then changes to show the new state: If the user continues to hold the left softkey (called click holding), the software will give the user an option as to whether to select an entry list. It provides a plurality of options, such as the option to switch to another display (for example, the chat history display described in FIG. 1, described in FIG. 10). Display group order buddy list, options to request a detailed description of the buddy (eg full name, personal nickname set (704, 705, etc.)), and options to show or hide fields (eg, short name indicator 907). ) To the user.

Once again, the technique of programming this functionality and connecting it once with clickking or clickholding is known in the prior art. It should be noted that the use of test strings to represent softkey labels is exemplary and intended only for the purpose of the present invention. Other forms of labels, such as graphic symbols, may be used.

If no buddy is selected, the right softkey is "Chat". One click or click holding in this content switches the user to chat the history display described in more detail with reference to FIG. When the user presses the push-to-talk button 101 (hereinafter referred to as push-to-talk), the voice indicator informs the user that the buddy has been selected first. In this case the display switches to the text message editing display described in more detail with reference to FIG. When the user pushes to talk, the display switches to the chat history and the user records the voice and forwards it to launch a new thread with the selected buddy.

10 shows a buddy list display with entries stored in groups. In a preferred embodiment, the group entry and this number buddy are listed first, followed by a list of ungrouped buddies. The individual entries are identical to the entries displayed in the alphabetical list except for a valid confirmation (annotation indicating membership to the grip). The group entry includes a group selection indicator 100 similar to the individual selection indicator 906 except that the group name 1005 and the group selection indicator can further indicate only selected and unselected states. This individual selection indicator indicates a partial selection as well. Referring to Fig. 10, the same square as in group 3 and group 4 (group selection indicator) is selected. Group 5 has an empty square representing partial selection. If no number is selected, no indicator exists at both the group level (or personal buddy level). To select a group, the user selects all the numbers one by one or directly selects the group. To partially select a group, the user can start by selecting a group and then not selecting more numbers. Alternatively, the user selects one or more numbers starting from the unselected group. The group entry may collapse (the number of groups stops appearing in the display). When the user highlights a collapsed group over a length of time, the group automatically expands to show the number. If the user moves to another group, the group display style changes back to collapsed state. If the user selects or does not select a group entry, all numbers in the group are automatically selected or not selected. The operation of the softkey labels 1003-1004 is similar to the softkey labels described in connection with FIG. When a group entry is highlighted (or when an individual entry within a group is highlighted), the user has an additional option to join the group: rename the group, remove the group or its number, add a new group or individual, and Manage options to zoom in or out.

It should be noted that in the preferred embodiment, multiple levels may be provided, but only one level of grouping is allowed (ie nested groups are not allowed).

Preferably, if the system supports a presence profile associated with the receiving user or group, so that the user highlights a plurality of buddy entries 908, the user indicator 904 and nickname 704 in the title bar may be assigned to a particular buddy. It changes to show the presence information of (or group of buddies). It should also be noted that if the information in the highlighted entry 908 is too long, the software uses other common techniques to scroll and expand the information or provide all the information to the user. It is understood that there are means by which the list (data, events, etc.) can be ordered and other annotations can be imposed on the entry.

11 illustrates a chat history display. The content 903 of the display is a single choice list that includes a plurality of entries representing the inbound chat message 500 received by the terminal 100 and the outbound chat message 400 sent by the terminal 100. The outbound chat message is preferably echoed back to the sender in all or part of the form of the inbound message (eg, the voice message does not include the delivered real voice). That is, the outbound chat message goes to the server complex for delivery to the intended recipient (s). In addition to delivering the message to the intended recipient (s), the broadcaster delivers a copy of the outbound message to the sending terminal (transmitter) as an inbound message. In some cases, the copy of the message (inbound message) to the transmitting terminal may not be the same as the message delivered (outbound). For example, voice content of an outbound voice message is not copied back to the terminal. That is, the text portion of the voice message is passed back as in the inbound message. In this case, the voice message has the text appended to it even though a specific character string or symbol is used. Of course, if voice / text conversion is useful, the actual voice content of the message can be converted into text and copied back to the transmitting terminal. In this way an entry is screened on the screen by the generation of a voice message. In an alternative method, the inbound message does not have the text of the outbound sent back to the transmitting terminal in the case, but the transmitting terminal echoes the text directly to the local display. In this way, the use of wireless resources is minimized.

A common problem in the technology of chat is the representation of successful transmission. The preferred approach for any notification of delivery is to send the outbound message 400 again (the echo inbound message 500 is sent to the message broadcaster 303 of the chat server complex 204 reliably). Alternatively, a representation is received by all recipients, which may be a text message located in the chat history with a message indicating that the message has been delivered. May be sent again when received by message broadcaster 303. Chat server complex 204 may send a receipt notification when all recipients have received the message. When is reached (for example, changing colors and / or fonts or decorated with symbols such as checkmarks), the original echo is the main one. In an alternative way, the echo for the user may be delayed until the broadcaster 303 confirms that all intended recipients have received a copy of the message. Is very long and the high delay variability between the delivery of multiple copy messages provides a presentation side effect that can be confusing to users in an environment where one or more recipients are not allowed to reach the other recipients. In this case, the sender may see his / her chat history display (see Fig. 11) and the response to the message before the echo, and several techniques can be developed to solve this problem. For example, the mobile terminal 100 or the server complex 204 may receive an echo and receiver in which the original message was delivered back to the user. You can delay the delivery or representation of the receiver response until it is received by.

Although not illustrated, at some point a user queues a system that has received or has not received a message. This implementation provides comparable information by delivering multiple receipts (if a copy is delivered to the user) instead of going to a system where the user has not delivered. Although this technique is simpler to support in the chat server complex 204, this technique requires more communications.

In the example of FIG. 11, each entry includes an attachment indicator 1104-1105 that indicates when some attached content (eg, documents and files, etc.) or transmitted voice is available, ie, sender 705. 803, and the shortest portion of the content or text (all text if the text is pinned to 2-3 lines). Although not shown in FIG. 11, it may be another indicator present in an entry, such as a locked entry indicator indicating that the entry appears in the chat history display until it is stored and unlocked in persistent storage 305. Less information can be displayed without a short name on the display.

When an entry is highlighted 1106, a plurality of nicknames 802 or 704 of the sender and other recipients are placed in the title bar 1101. If the list is too long, the content of the title bar 401 scrolls. Alternatively, a short name or other symbol may be used in place of the nickname of the title bar 1101. When the user selects an entry, all related chat messages in the same thread are of course highlighted 1103. If the selected entry is too long to display in its entirety and is selected over a period of time, the contents of the entry are automatically enlarged to display the full text content. In this case, when the user moves to another entry, the entry shrinks to fit within the originally allocated space of 2-3 lines of text. The actual number of allocated lines depends on the screen size. When a new inbound message 400 arrives, the new entry is automatically added to the list, for example at the bottom of the list. The bottom or buddy list entry 1107 is a specific entry that references the list of buddies currently selected in the buddy list display. The user can use the entry to start a new thread with a buddy. Only the bottom entry 1107 appears when the user has a selected body and includes an icon 1110 that distinguishes the entry from the commutation chat message entry. When the user selects the bottom entry 1107, the body list appears in the title bar 1101 in the same manner and the recipient highlights the regular tent of the chat history.

Left softkey label 1108 is a buddy. Clicking or clicking and holding the left soft key once switches the user to the buddy list display (FIGS. 9 and 10). The right soft label 1109 responds if the highlighted entry is a chat message entry. Otherwise, it is labeled light as before. Clicking the right softkey once causes the user to move to the manager editor display described in more detail with reference to FIG. 4. The target recipient of the message is obtained from the list of recipients of the first message entry 1106 or from the one associated with the buddy list entry 1107. If the highlight entry is a chat message entry 1106, clicking and holding the right softkey provides user options similar to those described in more detail with respect to FIG. Otherwise, if the highlighted entry is a buddy list entry 1107, the transmission for all actions is indistinguishable from the normal response for all actions in one click. When the user pushes-to-talk, the target recipient is compiled (i.e., either the sender to the message entry 1106 and the buddy of the buddy list entry 1107) and the title bar is described in more detail with reference to FIG. Is updated in a manner and delivery of the voice chat message is started.

It should be noted that the received voice is queued up if an inbound voice message is delivered while each history display is not visible to the user. In the current implementation, the most recently received voice message (or portion that is fixed in the available memory) is queued at the receiving terminal. In another approach, this queuing occurs in the server complex such that the receiver can request playback within a predetermined period of time. Moreover, queuing can occur at both the terminal and server side such that playback is requested from the server when a given voice message is no longer available at the terminal. The voice entry is a hypothetical recent voice entry but the associated voice is queued to prepare for automatic playback when the user returns to the chat history display. When the user switches back to the chat history display, the voice entry is automatically played back if it is visible on the screen. Only the last message received is automatically replayed. If the user returns to the chat history to record and send a voice chat message, playback is abandoned.

Clear delivery of voice messages to the user is problematic in the integration of conversations into a single chat history into multiple multiplication model threads. In current technology, it is difficult for a user to associate a voice with a particular thread. The system disclosed in this specification solves the problem in two ways. First, as described above, each voice message leaves an entry on the display. The entry link to the corresponding thread represents the sender and the list of other recipients of the message. However, this is not satisfactory if the user cannot see the display while listening to the voice message. For this reason, the system disclosed in the present specification uses a second technology related to the first technology. Preferably, when the user selects a thread, a voice message associated with the selected thread is automatically played for the user if it is not provided by the user. Voice messages that do not belong to the selected thread do not play automatically. Instead, the mobile terminal 100 provides a voice signal to the user to indicate that another incoming voice message is in a different thread. This user can be selected to play the message and request the system. Regardless of whether an incoming voice message is played, the text portion of the incoming voice message is provided on the display. This helps the user in choosing to listen to the message or to ignore it. Moreover optimization is possible. For example, the user may be given the option to drop a message. It is known that the transmitted voice data is dropped so that the server stops sending manager voice messages and starts sending the next message to queue (if not present).

Transmission technology can be optimized. For example, mobile terminal 100 can deliver a message to chat server complex 204 whenever a message selects a thread. The chat server complex 204 thereby suppresses delivering voice components of voice messages that are not included in the selected thread until the user desires to listen to the voice. This minimizes the transfer of large amounts of data to the mobile terminal 100, which may not be used.

12 illustrates a title bar of a chat history display when a user recognizes and sends an outbound voice message. This title bar includes a recording indicator 1201; A plurality of recipient nicknames 705 or 805 (not including the sender); And a single label 1203 indicating to the user that the person requests a conversation from an identified recipient. If the list of recipients is too long, the list scrolls but the recording indicator 1201 is fixed at that position. There may be a delay between times when the user pushes to request a record and when the system so approaches the user. Preferably, recording indicator 1201 is an icon that changes appearance (eg, color graphics symbol) to indicate when a user has or lost voice recording and transmission access. For a moment after the user releases the push-to-talk button 101, the tight bar changes back to the normal title bar 1101 on the chat history display.

13 shows a detail display of inbound chat message 500. Title bar 1301 includes sender presence indicator 904; Sender nickname 705 or 802 and a time stamp (if the message is sent or received). If the information in the title bar is too long, the nickname scrolls. In this case, the remaining indicator is preferably fixed. The content area 1303 can include an attachment indicator 1302, the full text of the message 1309, the separator 1304, (not including the sender or recipient) informing the user of the availability of an attachment or speech. It contains a plurality of entries representing other recipients. In the example shown in FIG. 13, each entry includes a user nickname set 703-705 or 802-803. Alternatively, each entry may include only a portion (nickname or short name) or other form of display identifier of a set of nicknames. Left softkey label 606 is cancel. Click the left softkey once and click holding again saves the display before exiting the display. Clicking on the right soft key holds the audio stream, playing the available voice, viewing or saving the available attachment, locking the entry to the chat history display, and storing the inbound chat message in permanent storage 305. ), User options such as moving to the next or previous chat message and replaying only to one or the other recipients. When the user push-to-talk it becomes a detail view display. The user goes to the chat history and starts talking to the sender (unless the user is the sender). In this case, reproduction of any queued voice is abandoned.

14 illustrates a text message editor display. In this example, title bar 1401 includes a single action label and a plurality of target recipient nicknames 704 or 802 indicating that a person contains a message. Title bar 1401 scrolls if the content is too long. The text entry area 1402 is provided below the title bar 1401 for composing a text message. Clicking once on the left soft key and clicking hold exits the display and abandons the content (if the previous display is restored instead of the detail display, except when the previous display is a detail display) and restores the previous display. Right softkey label 1403 is send. Click-holding the right softkey provides the user with a set of options such as a specification to check other messages for attachments of content (eg, ringtones, etc.) and the message and display the recipient's full details. Preferably, when push-to-talk, its content is abandoned. In other words, the user moves to the chat history and starts talking to the selected recipients. The reproduction of the queued voice is also abandoned in this case.

The invention is not limited to multiple forms of chat between people. Multi-model chat includes devices. There is a text-based chat system like that developed by Active Buddy. The system allows users to interact with creative services in the network using chat metaphors. Unlike these systems, however, the systems disclosed herein allow for chat conversations to use text and voice modes. For example, a user who wants to get the delivery status of a package forwards a voice message to the package delivery service presence. The voice may include at least a package identifier. Automated response services using speech recognition techniques known in the prior art determine user requests and construct responses. This response may be based on voice (eg, may convey a voice message indicating that the request cannot be understood) or may be textual (eg, the details of the package in its route to its destination). List). The service is available for user presence. The service informs the user of the current status of allowing the delivery of the detailed description to the desired pocket.

By the system of the present invention, the service comprises a command in which the mobile terminal 100 (e.g., initializing Ponsen) or the server complex 204 (relative to other services in the network) or a combination thereof may be satisfied. For example, individual chats with other users may want to initiate a telephone conversation. Preferably, the user requests the server complex 204 to initiate a telephone conversation by sending a command from the mobile terminal 100 to the server complex 204 containing the information needed to make a phone call between the sender and the target recipient. do. Server complex 204 initiates a request to a Voice Over (VolIP) telephone system. The system establishes the telephone access points that are closest to the end points so that senders and receivers route calls between these access points using common protocols such as Session Inititation Protocol (SIP) and Real time Transport Protocol (RTP). Set up a call by calling. The system uses a chat interface to collect and set up the details of the call (as described above) or initiate commands using common techniques known to the public. In an alternative method, server complex 204 sends a command to mobile terminal 100 containing the target phone number. The mobile terminal 100 initiates a telephone call with the next target. A telephone call is established to the mobile terminal 100 using the conventional technique.

The quality of the connection over the wireless data network may change over time. For example, a mobile user can move to an ineffective connection area where data connection is lost. The connection may then be reestablished if this range is available again, but in the process the mobile terminal 100 may obtain a new IP address. As a result, the server complex 204 may not be able to deliver the message to the mobile terminal 100. To address this, the system described herein describes a connection between a particular mobile terminal 100 and a server complex 204 using a session identifier. Each time the mobile terminal reestablishes the connection (eg, after losing due to coverage loss), the mobile terminal 100 uses the work period id of the blocked work period. Next, server complex 2044 rejoins the new connection to the reference session. If the mobile terminal 100 does not reconnect within the predetermined timeout period, the server complex 204 terminates this session. Other events that cause detachment may include lost session abort commands sent from the mobile terminal 100, and improper failure of the chat application and low battery in the mobile terminal 100.

Preferably, the session id is preferably used in place of the client id because the session that occurred within the server complex 204 is selected by the user to select a session to establish another session. In this way, message connections for terminated sessions can be removed from this system. Only transactions related to active sessions are maintained. In an environment where there are many message broadcasters 303 (ie, physical server hosts) in distributed server complex 204, clients may be added to different host computers. Using the session id provides a simple means to tell where the client is currently connected. In addition, when reestablishing a connection, the server complex 204 sends a sticky load that sends a reconnection client to physically reestablish a connection with the former host server based on the session id (even if the mobile terminal 100's IP address changes). Any known one may be used as a sticky load-balancing switch.

In addition, many wireless operator networks do not allow messages initiated by the network to reach the mobile terminal 100. As related to the system described herein, a network initiated message is a message paper that proceeds from the server complex 204 toward the mobile terminal 100 appearing to the network operator as not requested by the mobile terminal 100. This is typically the message broadcaster 303 delivering an unbound inbound message 500 to the recipient of the message. To solve this, the system uses keep-alive strategies. This strategy changes depending on the data transfer protocol established between the particular mobile terminal 100 and the server complex 204. This keep-alive strategy involves sending messages periodically from the mobile terminal 100 to the server complex 204. This keep-alive message appears on the mobile network as requested. The next message sent back to the mobile terminal 100 originates from the message sent to the mobile terminal 100 addressing the mobile terminal 100 transmitted in the keep live message. The frequency of keep live messages is a matter of design choice and the transport protocol used. When HTTP is moved to the transport protocol, the system uses a polling mechanism. Using this mechanism, it acts as a poll to determine if keep live messages are sent frequently and there are pending messages in the server complex. If there are pending messages, they are sent back in response to the polling request. TCP and UDP may use a keep live technique, such as simply sending the server complex 204 the working time id in a message for a very long time between messages without requiring a polling mechanism. Sending a keep live message can be optimized. For example, a keep live message should not be sent when an outbound message 400 is recently delivered from the mobile terminal 100 to the server complex 204.

Preferably, all messages sent from the server complex 204 to the mobile terminal 100 pass through the same router as the same physical host server to which the mobile terminal 100 is attached to the server complex 204. This ensures that the operator can process the message in response to the request of the mobile terminal 100. Other techniques for communicating appear to arise from locations such as address shopping and can be used by this system.

In addition, a keep-alive message operates in conjunction with the other techniques described above to inform the chat server complex 204 if the address of the mobile terminal has changed. This is particularly useful when UDP is used as the transport protocol. When all the cuff save messages are sent, the server complex 204 notes the address of the mobile terminal 100. If the address changes, the server complex 204 recombines this session id with the new address. Because of this, keep-alive messages can be an advantage of the system even if the operator does not block network maximized messages.

Since the server complex 204 does not have the latest address, it cannot deliver the message to the mobile terminal 100. That is, the address of the mobile terminal 100 is changed before the keep alive message is delivered. In this situation, the system keeps the undelivered message until the next Keep Alive message arrives. That is, it can drop the messages and inform the sender that it failed to deliver the message, or can deliver the message using an out of band mechanism such as the out-of band mechanism described with reference to FIG. 15. The subject of the currently developed wireless packet data network is a communication channel resource connection. While a wireless data connection is being established, the system (eg, 1xRTT of CDNA) may lose the ability to route phone calls and other wireless related service mobile terminals 100. Therefore, the preferred embodiment uses a back-off strategy based on predicting the user's involvement in the chat service. This back-off strategy uses a dynamic timeout scheme. For example, when the mobile terminal 100 provides an active update (i.e., an inbound message 500 and a chat history display with high likelihood of joining), the mobile terminal 100 is more than when the timeout length is updated. Significantly longer and less likely to participate than providing a buddy list display The purpose of the timeout is to inadvertently leave the chat application running to prevent incoming telephone calls or other communications from being sent to the user. The prompt informs the user that the connection between the mobile terminal 100 and the server complex 204 is about to be serviced, and the user can choose to cancel the action and maintain the connection. The connection is automatically terminated unless minimized within the held time for. If the terminal is not connected, which can no longer receive the instant message through the established packet data connection before.

Alternative separation schemes may be used. For example, a chat program running on a mobile terminal may be selected to periodically reconnect with the server complex 204 to know what message pending transmissions there are. Otherwise, the chat program on the mobile terminal is automatically disconnected. The message is delivered and the program updates the chat history display, as described above, to resume work until the user terminates the session or a timeout occurs as described above.

FIG. 15 illustrates how the overall system architecture of the wireless communication system including the components described in FIG. 2 extends with the legacy mobile terminal 1502. Within the content of the system described above, the legacy mobile terminal 502 may transmit and receive at least text messages over conventional mechanisms such as short message services (commonly referred to as SMS messages or SMS). However, unlike the mobile terminal 100, the legacy mobile terminal 1501 lacks the components required to communicate directly with the chat server complex 204 or directly participate in the described chat transactions.

To integrate the legacy terminal, the chat server complex 204 communicates with at least the SMS collector 1501 via a communication network 203 (such as the Internet or the World Wide Web). This SMS aggregator 1501 is a commercially available device that includes components required for an entry that is not directly integrated with a wireless carrier to inject an SMS message into one or more wireless carrier networks 202. SMS collector 1501 takes as input a component of the SMS (via an interface to the communication network). This description includes all components required to deliver a message to the target mobile terminal 100. This description includes the originator address, such as the mobile terminal 100 address, or a specific return address, known as a short or long code, a target address, such as the terminal 100 address, and the content of the message.

The SMS collector 1501 communicates with the target operator via the wireless carrier network 202 interface and sends an SMS on behalf of this requester. In this system the requestor is an agent or chat server complex 204 that acts instead.

The mobile terminal 100 enters the user's address of the legacy mobile terminal 1502. This is done in a hok manner, prompting for the address at the time the user creates outbound message 5400. The address in the content is the telephone number of the mobile terminal 1502. Alternatively, for a user who often targets a particular legacy mobile terminal, the system is provided for the user to build a buddy presence in a system that includes the presence data record 700 and the nickname data record 800. Conventional data collection and construction methods for processes that add legacy buddy or use ad-hoc addressing can be used.

The Regency Address is the recipient's id or real address of the Regency Buddy, which can be used in the same way as any other recipient id. It is located in the list of outbound message 400 and recipient ids 403 and 502 of inbound message 500. If a substantial address is used, the address presentation is typically distinguishable from non-legal addresses. This allows the system to process the address in a different way than the rest of the recipient id.

The registrar address may be part of the group communication with other legacy mobile terminals 1502 and other (non-legal) mobile terminals 100. Alternatively, the registrar address may be only an address supplied for one-to-one communication with the registrar terminal. The presence address may be part of initializing a new thread of a conversation or part of a response to an existing thread.

In the case of a hawk entry of the registrar address, the system must set the recipient fields 503-505 in the inbound message 500. The system places generic representations in these fields. If available, the system queues the public address book to find the actual name. Other techniques can be developed. For example, if information is considered personal and the system is not allowed to provide it early, this mobile terminal 100 (or server complex 204) can replace the information with a proxy representation.

The outbound message 400 that performs the registrar address is forwarded to the message broadcast 303 of the chat server complex 204. The message broadcaster 303 detects the legacy address of the legacy mobile terminal (either a support using the legacy buddy receiver id or an actual address). For each non-legal mobile terminal 100, the message broadcaster 303 builds an inbound message 500 as described above.

The broadcaster 303 forwards the SMS request to the SMS resin 1501 for each target region terminal 1502. To this end, the broadcaster 303 sets the originator address of the request of the SMS to the mobile address of the mobile terminal 100 of the sender that initiates the message. The SMS collector 1501 delivers the SMS on behalf of the chat server complex 204 to deliver the user to the legacy mobile terminal 1502.

The message sent to the legacy mobile terminal 1502 includes one or more original messages. Other information may be included in the message. For example, a message might contain a list of other recipients, thread schedules, latency, service provider identity, advertisements, and so on. For voice messages that cannot be delivered through an out of band messaging structure, the chat server complex 204 may replace voice content with textual content. If voice / text service is available, chat server complex 204 locates or terminates the obtained text message. Otherwise, chat server complex 204 can locate the representation of the discussion. For example, it droops voice parts and delivers only text parts similar to those displayed in the chat history display when an inbound voice message is received.

When the SMS is delivered to the recipient legacy mobile terminal 1502, an SMS application unique to the legacy mobile terminal 1502 running on the CPU in the terminal 1502, which is stored in the application store, interprets the SMS and identifies the user. The user reads the content of the message. The recipient may respond to the message using an SMS application on the legacy mobile terminal 1502. In this case, the application uses the originator address of the original inbound SMS supplied by the chat server complex 204 to build a response SMS targeting the sender. In this situation, the message is not passed back to the chat server complex 204. Instead, the response SMS proceeds directly to the target mobile terminal 100 via the network of the wireless carrier. When the response reaches the target mobile terminal 100, the chat application intercepts the message and displays it as part of the chat history display as described by the inbound message.

The mobile terminal prevents the chat application from accessing the out of band message system. In this case, the user responds using a native out of band application and moves a message (in whole or in part) between the two applications or otherwise manages the application's message.

The most recent SMS system includes components necessary to allow the chat server complex 204 to predictively implement information describing a plurality of SMS responses from the legacy mobile terminal 1502 (such as a list of threads, recipients, etc.). I never do that. Because of this, the reply SMS is not guaranteed to have an identity that causes the chat application program on the mobile terminal 100 to bind the inbound message to the existing thread. As a result, the message can appear in the chat history display as a new message in a new thread. Clients on the mobile terminal 100 under these conditions may generate a thread id instead of the legacy mobile terminal 1502. In the case of a user response, a new message and a Regency Mobile Terminal Address (originator address of the reply SMS address) are passed to the chat server complex 204.

In an alternate embodiment, the chat server complex 204 does not locate the sender's mobile address to the SMS originator address as described in the preferred embodiment. Instead, chat server complex 204 uses long code or alternatively short code. In this case, the SMS response from the legacy mobile terminal 1502 goes back to the server complex 204. The chat server complex 204 demultiplexes the message from the legacy mobile terminal 1502 of the code using various conventional techniques to couple the reply SMS to an existing thread. In this case, the message broadcaster 303 at the chat server complex 204 passes the message back to the thread's participants via the appropriate channel. For example, when another legacy mobile device joins a thread, the message broadcaster 303 delivers the message via the SMS collector 1501, as described above. The legacy integration law of the message broadcaster 303 may be performed at the mobile terminal 100 instead of the chat server complex 204. In this case, the mobile terminal 100 does not use the SMS collector 1501. Instead, the mobile terminal 100 can scan the SMS to one or more wireless carrier networks 202 for the targeted legacy mobile terminal (s) 1502.

Other out-of-band communication mechanisms may be used for email, multimedia management services (MMS). In this case another gateway type replaces the SMS collector 1501. Other delivery mechanisms allow the system to implement other information in the response message from the legacy terminal, allowing the system to bind the response to the reference thread.

 The problem with the mobile terminal 100 is the loss when the user starts another non-chat application on the terminal 100. For example, when a user on mobile terminal 100 receives an incoming telephone call, mobile terminal 100 drops data connection resources and suspends the chat program and / or otherwise, chat server complex 204. The chat application prevents it from meeting and communicating with the chat transact. In this case, the user will shut down the chat application if activity is hardly noticed or if the chat program is automatically disconnected to exhaust resources, as described above. For this reason, the consideration of the effective mobile terminal 100 for chat in accordance with the described system works in a manner that can be driven with the legacy mobile terminal 1501. The techniques described in the manner described above for integrating the chat environment with the legacy mobile terminal 1502 apply to this situation as well. Out of band delivery of messages (via SMS) acts as welcoming the user. This tells the receiver that the chat thread is working. The user is selected to reactivate the next chat program to resume the chat conversation. Alternatively, such a restart may be selected to participate using the available out of mechanism if it is not possible or convenient. If the chat application has access to incoming out of band messages, the chat application on mobile terminal 100 extracts the content and places them in the chat history display. This allows the recipient to respond to the sender. The response goes back to the out of band message or passes through the chat system with the outbound message 500 bands via the chat system described herein.

It is described that the current state 702 that appears in the mobile terminal 100 by the current state indicators 904 and 911 is available. Availability in such content indicates that a user can receive inbound message 500 (and in the form of any inbound message 500). Status indicating lack of availability in such content provides the fact that a user cannot receive inbound message 500 (or certain forms). Because of this, the system will drop the message targeting the user who is not available or store the message over time until the user is available again. For example, the system may attempt to deliver a message (even for the legacy mobile terminal 1502). In addition, the availability of the legacy mobile terminal 1502 (as defined by the current technology) may not be determined. The availability of availability (as defined by current technology) involves mobile terminals 100 and 1502 a lot of time for the user.

The current state 702 may perform availability as described above. In addition, system state 702 and current state indicators 904 and 911 are used to communicate with other information such as message delivery. To accomplish this, the user on mobile terminal 100 is provided with a presentation of the means the system uses to deliver a message, such as using in-band communication, via out-of-band methods such as wireless packet data or SMS, email. . This provides a presentation of the type or subset of messages being delivered. For example, an SMS text-only presentation indicates that the text portion of the message is deliverable to the target recipient via SMS. Because of this, the attachments (pictures) as well as the voice component of the outbound message 400 are not dropped or otherwise delivered to the target receiver. Such presentation is more suitable for mobile users. For example, it conveys costs related to message delivery, expected delays, and quality of service to the user.

16-17 illustrate a chat history / text edit display combination according to a preferred embodiment of the present disclosure. 16 shows a terminal screen 1600 in a first display mode. In the first display mode, screen 1600 provides graphical user interface (GUI) control 1604 as well as chat history 1602. As disclosed, other information may be provided to the screen 1600. As shown by way of example, a chat working time history 1602 containing a sequence of messages is posted by a participant in the current chat group. As described above, the displayed terminal identifies the sender and displays the posted text.

By operating the GUI control 1604, the user can selectively position the terminal screen 1600 in the second display mode. For example, in a preferred embodiment, the user selects a response from a message from the selection list control 1604 or a response to a configuration new message option. In the second display mode, screen 1600 continues the update and provides chat history 1702 concurrent with text editing area 1704. The chat history 1702 can continue to update and scroll on the screen while the text editing area 1704 is provided. The text editor residing on the mobile terminal can be operated such that the user can record one or more text messages in the edit area 1704 while simultaneously viewing the chat history 1702 as it progresses. GUI control 1604 allows a user to post a message configured in text editing area 1704 for the chat duration. These are displayed in the chat history 1702 in the following chronological order. They are preferably text editor area 1704 so that whenever the user communicates the message using GUI control 1604, the text editor area 1704 is removed and the screen automatically switches to the first display mode. May be deactivated by the user to close the chat history and the chat history 1702 may be enlarged to occupy the entire screen area.

Preferably, the screen 1600 may be switched back and forth between the first display mode and the second display mode using a user selectable area of the mobile terminal (GUI), such as a button or selection included in a pull-down menu or toolbar. have. Other user-operable switches such as momentary contact switches, pad button (s) and copyable softkey (s) are used to position the terminal display screen on both.

The functionality of the display mode shown in FIGS. 16-17 may be performed by software included in the mobile terminal and is preferably performed by a chat client application.

The foregoing is merely an example of an application of the principles of the present invention. Other configurations and methods may be performed by those skilled in the art without departing from the spirit and scope of the invention.
